my iphone 5s have a problem in some apps like head soccer,during the app it shutdown what i suppose to do ?

Double tap Home button and delete the app from multitask-list (Swipe UP the app's shapshot to delete).

Do a Reset: Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears. Note: You will not lose any data

Try again.

If no joy, delete the app completely and re-install the app.

Still no joy, write to the app developer or go to their forum and tell them about it.

Yes, deleting the app will delete the data.

But then the data is of no use if the app is not working.

You're welcome.
